was blocked (the output USRBLKED)
• the fact that at least one user is logged on (the output LOGGEDON)
Whenever one of the two events occurs, the corresponding output (USRBLKED or
LOGGEDON) is activated. The output can for example, be connected on Event
(EVENT) function block for LON/SPA.The signals are also available on IEC
61850 station bus.
